| 摘 要： | 本文所研究的梭梭(Haloxylon ammodendron(C.A.Mey)Bunge)、花棒(Hedysarum scoparium Fisch et Mey)、红皮沙拐枣(Caligonum rubicundum Bunge)和乔木状沙拐枣(C.arborescens Litv)是1979年人工栽植的。主要生长季节蒸腾速率(单位:μg/g.s)的平均值、花棒为170.7μg/g.s,红皮沙拐枣89.6μg/g.s.乔木状沙拐枣73.6μg/g.s,梭梭84.6μg/g.s.四种植物蒸腾速率从6——9月逐渐变弱,并且随着土壤水分含量的变化而变化。花棒和两种沙拐枣的蒸腾系数7月份较小,分别为46.6,87.0和46.5。

| Abstract: | Haloxylon ammodendron, Hedysarum scoparium, Calligonum rubicundum and C. arborscens we studied were afforestated in 1979. The average value of transpiration rate of Hedysarum scoparium,C. rublicundum,C. arborescens and Haloxylon ammodendron in whole growing season were 170.7ug/g.s,89. 6ug/g.s,73.6ug/g.s, and 84.6ug/g.s, respectively. The transpiration rate of above four plants became weaker from june to september. It varied accoding to the changing atomospheric environment factors and the water content of soil,as well.The transpiration coefficient of Hedysarum scoparium,C. rubicunium and C. arborescens were 46.6, 87.0,46.5,respectively in july. |
